Fig. 2 is the circuit theory diagrams of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2; A kind of infrared monitoring burglar alarm of the utility model; Comprise infrared ray sensor, coupling trigger, music integrated circuit and carrier wave multivibrator; The output signal of said infrared ray sensor is sent to music integrated circuit and carrier wave multivibrator through the control of coupling trigger, and the output signal of said carrier wave multivibrator is sent to the carrier signal decoding scheme through frequency-selecting amplifier.
Said infrared ray sensor adopts TTS-2102 type infrared ray sensor HWT; It is a kind of thermoelectric type pyroscan of being processed by the lithium carbonate crystal; The infrared ray that can detect moving object exactly and produced; And converting infrared heat energy to electric signal, the principal feature of this device is monitoring moving object, thereby reaches function such as antitheft.
If stationary object; Still can launch infrared ray; When TTS-2102 type infrared ray sensor HWT receives the infrared radiation of stationary object; Temperature can change, and then causes the change of spontaneous polarization strength, and result's appearance potential between perpendicular to two outside surfaces of crystal of spontaneous polarization direction is poor.But this moment, the bound charge on pyroelectric crystal surface receives the neutralization of internal freedom electric charge, its output terminal and no change current potential are occurred, so the alarm free sofar is given birth to.When having only the infrared radiation that produces when moving object to crystal, with the dissimulated electricity electric charge, make the crystal two ends occur one and change current potential during inner free charge has little time; Be noble potential of TTS-2102 type infrared ray sensor HWT output, diode D1 is ended, resistance R 2 two ends pressure drops reach more than the 6.5V; Make the 7th pin of JEC-2 coupling trigger IC3 become noble potential through capacitor C 2 couplings, when the 7th pin of JEC-2 coupling trigger IC3 was imported noble potential, its 2nd pin was then exported electronegative potential; Relay J obtains electric adhesive; Its normally opened contact JK transfers closure to, connects the working power of KD-5608 music ic IC4, and the output signal of KD-5608 music ic IC4 is after transistor Q1 amplifies; Promotion news Chinese percussion instrument Y sends and simulates the sound of barking; Play the warning effect, leave the investigative range of TTS-2102 type infrared ray sensor HWT up to mobile object, circuit recovers stationary state again.Constitute carrier wave multivibrator 4 by LM567 tone decoder IC1 and peripheral electric capacity 2C1, resistance 2R1, resistance 2R2 thereof simultaneously, its oscillation frequency is by the parameter determining of electric capacity 2C1, resistance 2R1, and carrier frequency is adjusted in the 150-300KHZ scope.Said frequency-selecting amplifier 5 is made up of elementary L1, electric capacity 2C2, the capacitor 2C3 of triode VT1, audio-frequency transformer (AFT) T; And the secondary L2, the electric capacity 2C4 that pass through audio-frequency transformer (AFT) T send data-signals to carrier signal decoding scheme 6; Be coupled on the AC network AC220V power lead and send by secondary L2, the electric capacity 2C4 of audio-frequency transformer (AFT) T, send alerting signals to carrier signal decoding scheme 6.、
Said carrier signal decoding scheme 6 is made up of the audio-frequency transformer (AFT) T1, LM567 ATD IC2, triode VT2 and the LED that connect successively; Carrier receiver is installed on sub-district property duty room, and the time constant of resistance 1R1, electric capacity 1C5 network has determined the voltage controlled oscillator of LM567 ATD IC2, when the carrier wave extension set when main frame sends 150-300KHZ carrier wave command signal; Be coupled to transformer secondary output L3 through electric capacity 1C1, audio-frequency transformer (AFT) T1; Transformer secondary output L3, electric capacity 1C2, electric capacity 1C3 form a carrier wave frequency selection network, and the signal after the frequency-selecting is coupled to the 3rd pin signal input part of LM567 ATD IC2 through electric capacity 1C4, after LM567 ATD IC2 decoding; By its 8th pin output terminal output low level; Make triode VT2 conducting, LED is lighted, and the carrier wave alerting signal of receiving extension set is described; The notifying cell operator on duty reaches the spot and handles.
An above-described preferred embodiment that is merely the utility model can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
